It would depend on the size of the window of the chart , the zoom level , and how "shrinked" or not the y axis of price is by the user and also on the % offset from the right end of the chart (the gap)

That means that with every change on the above you would have to recalculate the entire indicator . 

For instance : 

If you halve the window of the chart you will see less bars and that will lead to different levels because there will be less bars (b)

can i talk to you via whatsapp ?

You can post what you want here there is no need for that .

A further simplification if you will : 

You have a cake , you cut off a slice of that cake . 

You take that slice and you point at the right side of it and say "this is the right side of the cake" , but this is true for any slice whichever way you cut it.

You are not accounting for the entire cake the slice was a part of.

maybe you won't add arrow if people use it blindly so that you called it's scam. 
a humble request to you please add arrow when price cross only 50% level, and the coded file throw via messege , it willbe very helpful for me

You've ignored explanations of why this is dangerous for your account too 5 times already.

You're either not reading the replies , don't speak English or you are 100% aware of the danger.

Sending the code in private does not mean you can't sell it . 😊

Anyway if someone else wants to they can code it.

Cheers  ☕️

Edit : this is one of the only proper ways to do it more or less.

I need HEEEELP, please, it's URGENT...really !

Hello my friends,

This is a wonderful community, you are all so kind and smart. So I have this software, you know, to make money, I coded it (that's how we have to say when we found it on Internet right ?), and guess what, it's not working. I have it, but my bank account is not doing any money.

I don't want to learn, I don't want to pay, I don't want to read, I don't want to understand, just doing money. My bank account need it, but it's not working.

I would be so grateful, I will never forget the one who will help me.

Peace brothers.

why level plotted different place ?

 
maxtitu835 #:

why level plotted different place ?

Because this is the only backtestable way to do it . 

This way the calculation does not depend on : 

  • The chart window size
  • The gap from the right side
  • The adjustment of the y price axis
  • Which portion of the chart you are choosing to look at (or show in your screenshots)
  • The zoom level 

The first indicator was to showcase the issue .

What you can do next is find the look back value  (and maybe even the edge levels %)  that gives you the best signals and decide what will produce a signal by looking at the arrows sequence.

Symmetry between past and future is the first question you should ask about a strategy . Excluding the coin toss strategy

1st indicator levels stay same place on chart but 2nd indicator level doesn't match with  1st indicator levels

it's not a bug 

Use the 2nd version .

If you are Manchester city the 2nd version is Kyle Walker
